The completed studies analyze the cost of services, revenues and reserves, and recommend increases to the water and sewer rates. Increases are needed to fund the increased costs to purchase and pump water, to operate the system, and to fund the increased Capital Improvement Program to rehabilitate and maintain the City of Newport Beach's (City) water and sewer infrastructure for the long term. Staff is seeking City Council approval of both studies, for a public hearing to be set for November 14, 2023, and for authorization to send notices to Newport Beach property owners and water and sewer customers in compliance with state law. RECOMMENDATIONS: a) Determine this action is exempt from the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) and 15060(c)(3) of the CEQA Guidelines because this action will not result in a physical change to the environment, directly or indirectly; b) Approve the 2023 Water and Sewer Rate Studies; c) Direct staff to send a notice of proposed water and sewer rates to property owners and customers in compliance with Proposition 218 State Law; and d) Set the date of November 14, 2023, for the tabulation of protests and conduct a public hearing of proposed rates pending the results of the protest. DISCUSSION: Executive Summary: • Both the Water and Wastewater Enterprise Funds operate at a structural deficit, drawing down on net working capital reserves to fund the current Capital Improvement Programs. 12-1 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 2 • Rate studies were previously completed in 2017 and 2019; and future rate schedules are either expired or nearing expiration. • Increased replacement and rehabilitation of the water and sewer system pipes and components (the Capital Improvement Program) are needed, and are estimated to cost $45 million over the next five years. • Current and future inflationary costs are affecting the Capital Improvement Program, as well as all operational costs for materials, supplies, labor and electricity. The cost of pumping groundwater and purchasing imported water continues to increase. • Comprehensive Water and Sewer Rate Studies have been completed and the Finance Committee has reviewed the information. • Water and sewer rate increases are recommended to properly sustain the water and sewer system, with regular increases each year for five years. • The average rate increase for the first year is approximately $4.77/month for water and $2.20/month for sewer services, per household. If approved, water and sewer rate adjustments will commence on January 1, 2024, and will adjust annually on January 1 of each subsequent year. The total amount of a customer's bill will depend on the amount of water consumed. Based on the typical single-family residential customer with a 5/8" metered connection and consuming 10 HCF per month, the bills will increase as noted below: emu. Im �ML Gbh Single Family Residential Monthly Typical Bill (5/8" meter and 10 HCF) Water $63.92 $68.69 $74.19 $80.19 $86.19 $92.19 $ Increase $4.77 $5.50 $6.00 $6.00 $6.00 Sewer 7 $13.65 1 $15.85 $18.35 $21.35 $24.85 $28.35 $ Increase 1 $2.20 $2.50 $3.00 $3.50 $3.50 Rate Studv Backaround: Every few years, as the current rate schedules expire, a separate financial plan and rate studies are necessary to evaluate the water and sewer rates and to determine the charge for customers. Rate studies were previously completed in 2017 for sewer and in 2019 for water. These studies represent a best practice for determining utility rates that are fair, equitable and reflective of the demand placed on the systems by the customers. The City retained Black & Veatch Corporation to conduct the studies and assess the City's water and sewer rate structures. The goal was to ensure that the City's plans for critical infrastructure maintenance and for funding capital improvement projects with cash, are in alignment with the proposed rates. On May 11, 2023, and July 26, 2023, the Finance Committee delved into the water and sewer rate financial analysis of both Enterprise Funds. This included the reserve policy, the continued reinvestment needs for infrastructure replacement through the Capital Improvement Program, inflationary cost increases, and preparation for future droughts. Briefly discussed were typical steps and decision points for evaluating rates and rate structures. 12-2 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 3 Staff recommended, and there was concurrence with the Finance Committee, with maintaining a similar and simplified, easy -to -understand rate structure and moving fixed and variable rates to better match actual costs. On August 22, 2023, the City Council held a study session to review the water and sewer rate studies, and the proposed rates. The rate studies have been constructed with a financial plan that corrects the structural deficit and sufficiently funds operations, capital and reserves. Each fund has a reserve policy/target, which considers the various types of risk the utility faces. The reserve policies are similar to the previous policies; however, they better articulate the types and uses of the reserves. In general, even with the rates increasing, reserve calculations are below targets. The rates ramp up over the years, attempting to reach the target values by the fifth year (the amount is similar to the existing policy). Reserve Policy for the Water Enterprise Fund: • O&M Reserve — to cover day-to-day expenses and maintain sufficient funds to cover operating cash flows, periods of lower -than -expected water sales, or unforeseen cost. > 33% of operating expenses (or 4 months of expenses) • Capital Reserve — to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs. > 75% of 5-year average CIP • Rate Stabilization Reserve — to absorb lower -than -expected revenue due to short-term decreases in water sales in order to avoid large swings in rates charged to customers over time. > 30% of water use reduction (approximately $3 million) Reserve Policy for the Sewer Enterprise Fund: • O&M Reserve — to cover day-to-day expenses and maintain sufficient funds to cover operating cash flows, periods of lower -than -expected sewer sales, or unforeseen cost increases. > 25% of operating expenses (or 3 months of expenses) • Capital Reserve — to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs > 100% of 5-year average CIP Understanding the fees, the water and sewer bill. - Water and sewer users are billed for two components; the size of the meter, known as the fixed charge (or standby/ready-to-serve charge) and the commodity or water usage charge. Most users are billed every two months via a Municipal Services Statement. This statement also includes charges for the City's recycling program and the Fire Medics program for those that are subscribed. Some users receive a monthly bill and the future goal is to transition to monthly billing. 12-3 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 4 The rate studies looked at each of these charges, including their proportionality and recommended structured rate levels consistent with industry standard, in order to fairly and equitably recover the cost of providing water and sewer to the City's customers. The Finance Committee concurred with the goal of moving fixed and variable rates to better match actual costs. In order to accomplish this, most of the rate increases are reflected in the fixed meter charges as compared to the commodity charges. This approach better aligns with actual fixed expenditures, enhances the stability of the Enterprise Funds, and continues to maintain affordability and water conservation goals. Water System: The Utilities Department oversees the water system to provide safe and reliable water for drinking, irrigation and fire protection to Newport Beach residents, businesses and visitors. These essential services are accomplished through a strategic combination of dedicated in-house licensed staff operators (on -call 24 hours a day) and highly qualified contractors. Behind the scenes, the department is responsible for all water purchases/production, treatment, disinfection, water quality testing, regulatory compliance, field customer service, and emergency response. The water system is supported by the Public Works Department for the Capital Improvement Program projects and the Finance Department for utility billing and customer service. The system includes approximately 300 miles of water pipelines, 200 million gallons of water storage, 26,000 service connections (water meters), 17 water booster pumps, 42 pressure -reducing stations, 2,700 fire hydrants, 8,100 water valves, 12 interconnects and 4 groundwater wells. There are four main expenditure categories of the water enterprise that are important to providing water service: Purchasing/Pumping Water, Operations, Replacement and Customer Service. The cost to purchase and pump water includes the direct cost for the rights to pump groundwater and to buy imported surface water. The Operations category includes day-to-day operations and maintenance and is comprised of salaries, contract maintenance, repair materials, permits, outside agency fees, electricity, and professional services. Replacement includes the annual capital replacement or rehabilitation of aging infrastructure and recommended improvements per the Water Master Plan. Over $40 million in total annual capital improvements are planned over the next five years. Customer Service includes meter reading, invoicing, customer service, administration, and internal service charges. Water rates as shown in the table below and in the report, are proposed to be adjusted proportionally and increased each year for the next five years. The average residential customer, who uses approximately 10 billing units (7,480 gallons per month), is expected to see a $4.77 per month increase starting in 2024. This was the previously approved rate originally scheduled in 2019. In the following years, the monthly rate will increase monthly by $5.50 in 2025, $6.00 in 2026, $6.00 in 2027 and $6.00 in 2028. A billing unit is 100 cubic feet (one HCF) or 748 gallons. 12-4 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 5 Proposed 5-year (Potable) Water Rates: Effective Date Fixed Service Charges ($/Month) Meter Size 0: 5/8", 3/4" 25.22 27.09 31.59 36.59 41.59 46.59 1 " 39.09 41.99 50.07 58.30 66.53 74.75 1-1/2" 73.69 79.15 96.29 112.59 128.88 145.16 2" 115.23 123.76 151.74 177.74 203.71 229.65 3" 305.61 328.23 405.92 476.32 546.65 616.89 4" 523.69 562.45 697.06 818.33 939.47 1,060.46 6" 1,112.15 1,194.45 1,482.68 1,741.22 1,999.48 2,257.39 8" 1,942.91 2,086.69 2,591.80 3,044.12 3,495.95 3,947.18 Usage Charge Water Usage 3.87 4.16 1 4.26 4.36 4.46 4.56 Fire Service Water Rates: The City's water system also has approximately 460 fire service customer connections. These are typically the large, red, above -ground pipes and valves seen in front of businesses or in parking lots. This pressurized water is supplied on a standby basis to provide additional fire -fighting water if needed by the property beyond the fire hydrant. The fire service water rates recover the proportional cost to provide fire protection capacity, metering and billing. As seen in the table below, especially for the larger meter sizes, rates have been increased and adjusted to be compliant with industry "proportionality" standards, ensuring compliance with Proposition 218. Simply put, the larger the pipe connection, the larger the burden on the system to meet peak demands. Most fire services do not use water regularly. However, if water is used through the fire service, the standard commodity potable water rate is used.

The City purchases recycled water from the Orange County Water District (OCWD) through a project known as Green Acres Project. The recycled water rates recover the direct costs to purchase the recycled water, and the proportional costs regarding capacity, metering and billing. Proportionality standards also apply to these recycled meters and in this case, the fixed rates are adjusted and reduced. Certain users also have exclusive pump stations to increase the flow and pressure of the water to meet watering needs. Those users are charged the direct charges associated with the pump stations. In general, recycled water remains less expensive than potable water. Recycled water rates are shown below: Current VI Approved I New New New New Date Fixed Service Charges ($/Month) Meter Size 1.1 18.41 19.78 21.85 23.06 24.16 25.25 1-1 /2" 32.35 34.75 39.84 42.10 44.15 46.16 2" 49.09 52.73 61.43 64.95 68.13 71.25 3" 125.81 135.12 160.38 169.69 178.05 186.25 4" 213.68 229.50 273.72 289.66 303.96 317.97 6" 450.80 484.16 579.56 613.40 643.72 673.42 8" 785.55 843.69 1,011.34 1,070.43 1,123.38 1,175.23 Sewer (Wastewater) System: The Utilities Department oversees the operation of the City's sanitary sewer system. Hidden below the ground, a properly functioning system provides a crucial service to Newport Beach residents, businesses and visitors, and protects the environment. This essential service is also accomplished through a strategic combination of in-house, licensed, staff operators (on -call 24 hours a day) and highly qualified contractors. Behind the scenes, the department is responsible for cleaning, pumping and repairs of the collection system. Sanitary sewer flows are collected from homes and businesses in Newport Beach and transported through more than 25,000 laterals, 200 miles of gravity sewer mains, and 5 miles of pressurized force sewer mains by way of 21 pump (lift) stations to the Orange County Sanitation District. The sewer system is supported by the Public Works Department for the Capital Improvement Program projects and the Finance Department for utility billing and customer service. 12-6 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 7 There are four main expenditure categories of the sewer (wastewater) enterprise that are important to providing sewer service: Cleaning Operations, Pump Station Operations, Repairs/Capital Replacement, and Customer Service. Cleaning Operations include the cost to regularly clean and video tape sewer lines. The public may be familiar with the department's large, yellow vacuum trucks. Pump Station operations includes the day-to-day operation, inspection and repairs of the City's 21 pump stations that lift and pump wastewater from low-lying areas. Repairs include the scheduled and unscheduled dig out spot repairs of the underground pipelines and laterals. Capital Replacement includes the larger -scale replacements and rehabilitation of pipelines and pump stations as recommended per the Wastewater Master Plan. More than $5 million in total annual capital improvements are planned over the next five years. Customer Service includes meter reading, invoicing, customer service, administration and internal service charges. Sewer rates as shown in the table below and in the report, are proposed to be adjusted proportionally and increased each year for the next five years. The average residential customer, who uses approximately 10 billing units, (7,480 gallons per month), is expected to see a $2.20 per month increase starting in 2024. In the following years, the monthly rate will increase by $2.50 in 2025, $3.00 in 2026, $3.50 in 2027 and $3.50 in 2028. A billing unit is 100 cubic feet (or 1 HCF) or 748 gallons.

For those properties, the City does not have immediate access to their water use for billing purposes. The best practice is to estimate an average based on the meter size, as explained in the official report. Hence, these users only receive a flat fee. As noted and approved by the City Council on July 25, 2023, these properties, for the second year in a row, will be billed through the property tax roll. 12-7 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 8 Proposed 5-vear Sewer Only Customer Rates Sewer Only Customers, Fixed Service Charge, (no Use Charge) ($/Monthly) Meter Size 5/8", 3/4" 13.10 15.86 18.36 21.35 24.85 28.36 1 " 15.34 18.51 21.11 24.20 27.80 31.41 1-1 /2" 46.14 53.99 58.88 64.52 70.91 77.30 2" 47.54 59.27 65.31 72.34 80.39 88.43 3" 122.10 137.68 147.63 158.83 171.29 183.74 4" 216.25 238.35 253.06 269.27 286.97 304.67 6" 381.07 413.21 435.48 459.51 485.26 511.00 8" 383.21 418.49 441.91 467.33 494.74 522.12 10" 389.20 423.77 448.33 475.15 504.21 533.25 Next Steps and Proposition 218 Requirements: Upon incorporation of the City Council's recommendations and direction to send Proposition 218 notices, pursuant to California Constitution Article XIII D, Section 6, staff will prepare and send notices to all property owners (and as a courtesy to all customers, i.e. tenants) that receive water and/or sewer service from the City. There will be a 45-day public notice period at which time, property owners and customers may send written protests for consideration of the City Council. Protests from property owners will be tallied at the public hearing tentatively set for November 14, 2023. Notwithstanding a majority protest, City Council can consider verbal testimony from anyone and written protests from non -property owners and decide to approve the rates. If the rates are approved, and the amended fee schedule adopted via resolution, the proposed water and sewer rates would become effective on January 1, 2024, and for every year thereafter with the final scheduled adjustments occurring January 1, 2028. FISCAL IMPACT: The current adopted budget includes sufficient funding for completion of the studies and the public noticing. The cost of the studies is approximately $100,000 and the cost of the public noticing (Proposition 218 mailed notice) is estimated at $15,000. As currently budgeted, the Water Enterprise Fund and Wastewater Enterprise funds are now operating at a structural deficit, drawing down on net working capital reserves. If the proposed rate increases are approved, rates would be adjusted and generally increase each year for five years, starting in January 2024. The rate increases will fund the necessary Capital Improvement Program, the increased inflationary cost of maintenance and operations, and the cost to purchase and pump water and stabilizing the enterprise funds. ENVIRONMENTAL REVIEW: Staff recommends the City Council find this action is not subject to the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential for resulting in physical change to the environment, directly or indirectly. 12-8 Approval of 2023 Water and Sewer Rate Studies and Setting of Public Hearing for Water and Sewer Rates September 26, 2023 Page 9 NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).

The City has not requested Black & Veatch to make an independent analysis, verify the information provided to us, or render an independent judgment of the validity of the information provided by others. Because of this, Black & Veatch cannot, and does not, guarantee the accuracy thereof to the extent that such information, data, or opinions were based on information provided by others. In conducting these analyses and in forming an opinion of the projection of future financial operations summarized in this report, Black & Veatch made certain assumptions on the conditions, events, and circumstances that may occur in the future. The methodology utilized in performing the analyses follows generally accepted practices for such projections. Such assumptions and methodologies are reasonable and appropriate for the purpose for which they are used. While we believe the assumptions are reasonable and the projection methodology valid, actual results may differ materially from those projected, as influenced by the conditions, events, and circumstances that occur. Such factors may include the City's ability to execute the capital improvement program as scheduled and within budget, regional climate and weather conditions affecting water demand, and adverse legislative, regulatory, or legal decisions (including environmental laws and regulations) affecting the City's ability to manage the system and meet water quality requirements. BLACK & VEATCH I Legal Notice LN-1 12-15 City of Newport Beach, CA I Water Rate Study 1.0 Executive Summary The City of Newport Beach (City) commissioned Black & Veatch Management Consulting, LLC (Black & Veatch) to perform a Water Rate Study (Study) for its Water Utility. The Study included the development of a five-year financial plan, a cost -of -service analysis, and the design of rates. The specific objectives of the Study were to: Evaluate the adequacy of projected revenues under existing rates to meet projected revenue requirements. Develop a sound financial plan for the Water Utility covering five years for ongoing operations and planned capital improvements. Allocate the projected revenue requirements to the various customer types in accordance with their respective service requirements. Develop a suitable rate schedule that produces revenues adequate to meet financial needs while recognizing customer costs of service and regulatory considerations such as Proposition 218 and applicable judicial decisions. 1.1 Financial Plan The City operates the utility as an individual self-supporting enterprise. As such, the utility develops a financial plan that provides sufficient revenues to meet all operation and maintenance (O&M) expenses, water purchases, debt service requirements, capital improvements from current revenues, and other expenditures. The Study develops a financial plan that projects operating revenue, expenses, and capital financing costs for the utility over a five-year planning period beginning fiscal year (FY) July 1, 2023, and ending June 30, 2028. The financial plan projects future rate revenues under existing rates, O&M expenses, debt service payments, payment to other City departments for services provided, and capital improvement program (CIP) requirements. In the projection of rate revenues, annual projections of customers and water consumption rely upon the City's historical data and estimates of growth. Additionally, the Water Utility's forecast incorporates efforts to continue meeting the conservation goals established by the State and the City's Water Shortage Contingency Plan. Black & Veatch worked with the City to develop a proposed financial plan to support the Water Utility's O&M and capital needs, while minimizing impacts to customers. The financial plan supports the following activities: Operation and Maintenance Expenses: The Water Utility anticipates O&M expenses to increase from $30.4M in FY 2024 to $34.9M in FY 2028. Water production and purchases account for most of this increase, averaging 46% of O&M expenses. Debt Service: The Water Utility has no existing debt service, and no future debt is planned. Capital Improvements: The Water Utility plans to execute an average of $8.OM annually in capital projects from fiscal year (FY) 2024 to FY 2028. Reserves: The Water Utility plans to continue funding the operating fund reserve, capital fund reserve, and rate stabilization fund reserve. BLACK & VEATCH I Executive Summary 12-16 City of Newport Beach, CA I Water Rate Study The operating fund reserve is to help cover fluctuations in day-to-day expenses and to pay for additional imported water purchases if groundwater becomes unavailable. The scheduled target is 120 days of O&M expenses. The capital fund reserve is to help maintain enough funds to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs. The scheduled target is 75% of the annual CIP. The rate stabilization fund reserve is to help mitigate future increases during revenue shortfalls that might result from lower -than -expected water sales. The scheduled target was established in FY 2019 to be equal to revenue loss due to a 30% of water use reduction, which equates to Stage 3 in the City's Water Shortage Contingency Plan. The Water Utility is proposing revenue adjustments to allow the enterprise to meet operating and capital needs and reserve targets, as shown in Figure 1-1. Figure 1-1 Water Enterprise Fund Financial Plan Water Enterprise Financial Plan 2024 2025 2026 2027 2028 � O&M � [apial Projects —43�— Revenue 'Reserves J 1.2 Rate Design The Right to Vote on Taxes Act, also known as Proposition 218, was passed by California voters in 1996 and added Article XIIIC and Article XIIID to the California Constitution. These articles provide the regulatory framework that guides and informs the rate -setting process. The cost -of -service analyses provide the cost nexus for the proposed rate structures. The regulatory framework helps ensure cost recovery is proportionate to the cost of providing the service.' To minimize impacts, retain simplicity, and ensure the reasonable stability of revenue, Black & Veatch recommends the following rate structure. Monthly Fixed Charge: The Water Utility should retain the monthly fixed charge based on meter sizes for all customer types. The monthly fixed charge recovers portions of fixed cost elements such as ' Black & Veatch is not a legal firm and interpretations of the legal requirements under Proposition 218 should be reviewed by legal counsel. BLACK & VEATCH I Executive Summary 12-17 City of Newport Beach, CA I Water Rate Study operating and capital components, meter maintenance and services, meter reading, issuing bills, and maintenance and capacity costs associated with public fire protection. Consumption Charge: The Water Utility should maintain the uniform consumption charge for all customer types. The consumption charge recovers costs associated with the base and extra capacity demands. Fire Service Charge: The Water Utility should continue to utilize the fire service charge based on meter size for private fire service connections. The fire service charge will recover maintenance and capacity costs associated with private fire protection costs. .3 Proposed Water Rates Table 1-1 summarizes the Water Utility's recommended five-year rate schedules for water and private fire protection services. Table 1-2 presents the recommended recycled water rates. Rates are effective January 1st of each calendar year. The rates developed in this study focused on FY 2025 through 2028 as rates effective on January 1, 2024, were previously approved by City Council in the 2019 rate case2.

Black & Veatch used industry standard principles for equitable cost -of -service allocations to calculate the proposed rates. Detailed explanations for these calculations are provided in the remainder of this report. BLACK & VEATCH I Executive Summary 12-19 City of Newport Beach, CA I Water Rate Study 2.0 Introduction 2.1 Purpose The purpose of this report is (1) to project the future revenues of the Water Utility under existing rates and charges, project operating expenses and capital financing revenue requirements, and to examine the adequacy of projected revenues to meet these revenue requirements through FY 2028; (2) to allocate these revenue requirements, or costs of service, for a representative test year to the various customer types in accordance with the respective service requirements that each class places on the systems; and (3) to develop a suitable schedule of water rates that will produce revenues adequate to meet the financial needs of the utility on the basis that recognizes customer costs of service and practical bill impact considerations. 2.2 Water System The Water Utility provides water services to over 26,000 residential and non-residential customers. The City obtains potable water from three primary sources: local groundwater through Orange County Water District (OCWD), imported water from the Colorado River and/or the State Water Project through the Municipal Water District of Orange County (MWDOC), and recycled water purchased from OCWD. The water system infrastructure consists of 302 miles of transmission and distribution mains, four wells, three storage reservoirs with a total capacity of 202 million gallons, and five pump stations. The City relies on approximately 75% groundwater, 22% imported water, and approximately 3% recycled water. 2.3 Methodology The rate -setting methodology employed by Black & Veatch is consistent with industry guidelines established by AWWA's Principles of Water Rates, Fees, and Charges, M1 manual (M1 Manual). The manual is nationally recognized and provides recommendations and generally accepted practices in the water industry. The M1 Manual is used by rate practitioners as guidance on rate -making practices that can be used to address the unique circumstances of the communities served. An overview of the methodology is outlined below. 2.3.1 Financial Plan Financial planning compares the projected revenues of the utility under existing conditions to its projected operating expenses and capital expenditures. This step tests the adequacy of the current rates to recover the utility's forecasted costs. If shortfalls occur, revenue increases are recommended until the utility is financially stable. 2.3.2 Cost -of -Service Analysis The cost -of -service analysis builds a link between the utility's cost of service and Financial Planning Establish operating and capital financing plans that fullyfund oil activities Cost of Service Analysis Perform a cast -of -service anakysis to determine if cost allocations are fair and equitable among custorer classes the proposed rates for each customer type. This process takes individual budget cost items and allocates them based on their function. Organizing the budget in terms of end function allows the creation of a nexus between the budget cost item and the rate. BLACK & VEATCH I Introduction 12-20 City of Newport Beach, CA I Water Rate Study 2.3.3 Rate Design Rate design involves developing a rate structure that equitably and proportionately recovers costs from the customers. The rate structure should reflect a customer group's demand profile and be resilient and flexible enough to handle changing costs (i.e., operating and/or capital) and demand scenarios (i.e., customers change their demand on the system by contributing less or more flow). Rate equity is inherently built upon each customer's Rate Design Review the existing rate structure + - and design proposed rates that provide adequate revenues relative use of the system. By designing different rate components, the utility can balance affordability and equity. 2.3.4 Rate Adoption In California, public utilities must meet procedural requirements for adopting new or increased rates for property -related fees under Proposition 218. Proposition 218 states that the utility must hold a public hearing to consider the proposed rates and provide written notice to all customers at least 45 days before the hearing. Any property owner or tenant directly liable to the public agency for payment of the property - related fees may submit a written protest to the new or increased rates until the close of the public hearing. The City Council may not adopt the proposed new or increased rates if property owners or tenants directly liable for payment submit written protests on behalf of more than 50% of the properties upon which the proposed rates may be imposed. BLACK & VEATCH I Introduction 2-2 12-21 City of Newport Beach, CA I Water Rate Study Water Utility 3.0 Revenue and Revenue Requirements To meet the costs associated with providing water services to its customers, the Water Utility derive revenue from a variety of sources, including water and recycled water user charges (rates), reimbursements, establishment fee, connection charges, turn -on charges, penalties, interest earned from the investment of available funds, and other miscellaneous revenues. The Water Utility is constantly looking for other sources of revenue, such as grants, to fund infrastructure investments. Black & Veatch has projected the future revenue generated in the Study by analyzing historical and future system growth in terms of the number of accounts and billed water consumption. This section also projects the expenses, or revenue requirements, necessary to operate and maintain the system, invest in capital improvements, make debt service payments, and cover other water systems expenses. 3.1 Customer and Water Consumption 3.1.1 Number of Customers The City provides potable water services to 26,000 residential and non-residential customers and recycled water services to six customers. All customers connected to the water and recycled water systems do so through metered connections. The City bills customers based on the size of the metered connection and the consumption. Since the City bills customers based on the metered connection, the analysis included a review of historical accounts for customers and anticipated growth within the City. The City has seen a slight decline in population between 2020 and 2023 based on the State of California Department of Finance, E-5 Population and Housing Estimates. The analysis herein projects the total number of accounts to remain steady for the entire study period. Table 3-1 summarizes the projected number of accounts for the Water Utility.

In determining the projected water consumption, Black & Veatch analyzed historical water consumption patterns in conjunction with the 2020 Urban Water Management Plan, future water conservation requirements set by the City's Water Shortage Contingency Plan, the continual requirement of Senate Bill (SB) 7x-7 and mandatory water conservation mandates. In 2016, after years of drought conditions, the State of California mandated cutbacks to all water purveyors to reduce water usage by 25%. This action led to a significant decline in water consumption. In 2017, the State of California formally lifted the water restrictions as it declared the drought over. Yet the mandatory cutback had a lasting effect on water conservation habits, leading to a continued decrease in overall water consumption. In 2020, California again entered a drought. In 2022, to conserve water, the State of California adopted emergency regulations to increase water conservation and required urban water suppliers to implement Level 2 of their Water Shortage Contingency Plans. Shortly thereafter, the City moved to Level 2. In 2023, after record rainfall and snowpack levels, the State of California eased the drought restriction. Soon after, the City repealed Level 2 resolutions, providing relief to the community while promoting the wise use of water. Many factors contribute to the City's annual consumption. The City's primary goal is to provide its residents with safe and reliable drinking water and encourage water conservation. Providing recycled water to existing and new customers is important for the City in supplementing potable water use. Overall, customers have done well to increase efficiency in the use of water resources. Recognizing all the various factors contributing to water demand patterns and understanding the state requirements and water consumption has stabilized, the projected billed water consumption is expected to remain steady for the Study period. The City currently bills water consumption in hundred cubic feet (HCF). Table 3-2 Annual Billed Water Consumption Recycled Water Water 1 All Customers (HCF) 5,439.576 244,511 2 Total (Acre -Feet) 12,488 561 3.2 Revenue under Existing Rates Water user rates serve as the Water Utility's primary revenue source. Therefore, the level of future rate revenue is important in developing a long-range financial plan. Future water rate revenues are calculated using the system growth for the number of accounts and billed water consumption multiplied by the applicable existing rates. Since accounts and billed water consumption have no growth, rate revenue is expected to remain constant. Table 3-3 presents the rates in effect for FY 2024 (effective January 1, 2024), which were approved by City Council on November 19, 2019, as part of the City's 2019 Rate Study. The rates are composed of monthly fixed and uniform consumption charges. The monthly fixed service charge differs for water, recycled water, and private fire service. The consumption charge differs for water and recycled water. In addition, one recycled water customer pays a pump station charge associated with energy costs from a recycled water pump station that services them.

In 2019, the City completed its 30-year Water Master Plan, which identified $165.2M in capital projects in 2018 costs. Incorporating cost escalation over the 30 years, the City had planned to spend roughly $7.2M each year. Unfortunately, the City has had to readjust this annual spending by 5% each year due to higher -than -expected inflation. Therefore, the City plans to spend $40.2M over the Study period. Table 3-7 summarizes the CIP for FY 2024 through FY 2028. The Water Utility is composed of many functions, of which transmission and distribution pipelines are significant elements. Therefore, of the total $40.2M, transmission and distribution pipelines account for 84.2% of the total projects. The City examines the water infrastructure system annually; therefore, CIP might change based on the current need.

The other accounts are the Enterprise CIP, Capital, Operating Reserve, and Rate Stabilization (See Section 3.7 for further explanation on Operating Reserve and Rate Stabilization Reserve.) The Enterprise CIP and Capital account transfers represent money to cover planned CIP project expenditures. These transfers do not represent direct operating expenses for either enterprise; therefore, they are treated as "below -the -line" cash flow items and not included as O&M expenses. 3.7 Reserves A utility typically establishes reserves for several reasons, such as to cover shortfalls in operating revenues, maintain strong bond ratings, cover day-to-day operating costs, and ease the burden on ratepayers associated with large rate increases. Per the reserve level recommendations, the Water Utility will maintain the following three reserves: Operating Reserve represents working capital maintained by the Enterprise Fund to cover day-to-day expenses and maintain enough funds to cover accounts receivables, periods of lower -than -expected water sales, or unforeseen cost increases such as to pay for additional imported water purchases if groundwater becomes unavailable. The reserve will maintain a minimum balance of 120 days of operating expenses once fully funded. Capital Reserve represents funds to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs. Once fully funded, this reserve will maintain a minimum balance of 75% of the annual planned CIP. Rate Stabilization Reserve represents funds used to absorb lower -than -expected revenue due to short-term decreases in water sales. This reserve stabilizes water rate revenue and is an effort to avoid wide swings in rates charged to customers over time. When fully funded, the reserve will maintain a minimum balance of 30% of water use reduction. Appropriate reserve levels help the Water Utility with liquidity, provide operational flexibility, and demonstrate fiscal responsibility to the rating agencies, which allows the City to access lower -cost funds if needed. Figure 3-1 shows the fund balances for all accounts after the recommended rate increases compared to the total target fund balance.

To fully understand the current condition of the Water Utility, it is important to examine the cash flow projections under the status quo scenario. As shown in Figure 3-2, the status quo conditions would project that the Water Utility would operate from an annual deficit position, thus requiring the use of reserves to keep operating. In this scenario, the Water Utility would not impose any revenue increases over the Study Period and continue to incur O&M expenses, pay for the execution of the planned CIP, and transfer to reserves.

The revenue increases represent the total revenue adjustment BLACK & VEATCH I Revenue and Revenue Requirements 12-28 City of Newport Beach, CA I Water Rate Study needed to meet revenue requirements. The revenue adjustment does not represent adjustments to the individual rates but reflects the overall level of revenue needed to meet the Water Utility's obligations. The suggested revenue increases help the Water Utility meet the following goals: Meet budgeted operating obligations in the five FYs. Meet planned capital investments in the five FYs. Build up the operating reserve, capital reserve, and rate stabilization to reach their targets. Table 3-8 summarizes the proposed Enterprise Fund for the Study Period. The Enterprise Fund consists of 1) Revenue and 2) Revenue Requirements. Revenue Line 1 is the revenue under existing rates. Lines 2 through 6 are the additional revenues generated from the required annual increases. The additional revenue generated directly reflects the number of months the increase is effective for; therefore, the amount might be calculated at less than that stated amount. Line 8 is the total revenue generated from user charges. Line 11 represents other operating revenues. Line 12 represents the total revenues for the enterprise. Revenue Requirements Line 14 represents O&M expenses. The O&M expenses include water production and water purchase. Lines 15 and 16 represent capital expenditures within the capital accounts.

An equitable rate structure allocates the capture of revenue requirements to customer types based on the quantity of water consumed, peak flows, the number of customer connections, and other relevant factors. In analyzing the Water Utility's cost of service for allocation to its customer types, Black & Veatch selected the annual revenue requirements for FY 2025 as the test year requirements to demonstrate the development of cost -of -service water rates. FY 2024 rates were already approved in the last rate study. Table 4-1 summarizes the total costs of service that need to be recovered from water user rates for FY 2025.

BLACK & VEATCH I Cost -of -Service Analysis 12-32 City of Newport Beach, CA I Water Rate Study 4.2 Functional Cost Components The first step in conducting a cost -of -service analysis involves analyzing the cost of providing water and recycled water service by system function to allocate the costs to the various customer types properly and, subsequently, design rates. As a basis for allocating costs of service among customer types, the study separates costs into the following five basic functional cost components: (1) Supply, (2) Base, (3) Extra Capacity, (4) Customer, and (5) Direct Assignment, described as follows: Supply costs are associated with paying OCWD and MWDOC for groundwater and import water, respectively. Base costs represent operating and capital costs of the system associated with service to customers to the extent required under constant or average annual load conditions without the elements necessary to meet water consumption variations or peak demands. Extra Capacity costs represent operating and capital costs incurred to meet peaking demands. Peaking demands represent water consumption more than the average rate of use. Customer costs are those expenditures that tend to vary in proportion to the number of customers connected to the system. These include meter reading, billing, collecting, accounting, maintenance, and capital costs associated with meters and services. Directly assigned costs are specifically identified as those incurred to serve specific customers. These costs include conservation, recycled water supply and pump station, and fire protection. 4.3 Allocation to Cost Components The next step of the cost -of -service process involves allocating each cost element to functional cost components based on the parameter or parameters having the most significant influence on the magnitude of that cost element. O&M expenses are allocated directly to appropriate cost components. A detailed allocation of related capital investment is used as a proxy for allocating capital and replacement costs. The separation of costs into functional components provides a means for distributing such costs to the various types of customers based on their respective responsibilities for each type of service. 4.3.1 System Base, Max Day, and Max Hour Allocations The water system consists of various facilities designed and operated to fulfill a given function. For the system to provide adequate service to its customers, it must be capable of meeting the annual volume requirements and the maximum demand rates placed on it. Because not all customers and types of customers exert maximum demand simultaneously, the capacities of the various facilities must meet the maximum coincidental demand of all customers. Each water service facility within the system has an underlying average demand exerted by the customers to whom the base cost component applies. For those facilities designed solely to meet average day demand, 100% of the costs go to the base cost component. Extra capacity requirements associated with coincidental demands more than average use consist of maximum daily and maximum hourly demand subcomponents. The first step in determining the allocation percentages for volume -related cost allocations is to assign system peaking factors. The base element equals the average daily demand (ADD) and is assigned a value of 1.0. Based on the City's 2019 Water Master Plan, the Water Utility's maximum day (max day) demand is 1.85 times the ADD. The maximum hourly (max hour) demand is 2.6 times the ADD. The costs associated with facilities required to meet maximum day demand are allocable to base and maximum day extra capacity, as shown below for the Water Utility. Base = (1.0/1.85) x 100 = 54.1 % BLACK & VEATCH I Cost -of -Service Analysis 12-33 City of Newport Beach, CA I Water Rate Study Max Day = (1.85 — 1.0)/1.85 x 100 = 45.9% These calculations indicate that the average or base use requires 54.1 % of the capacity of facilities designed and generated to meet maximum day demand, and the remaining 45.9% meets maximum day extra capacity requirements. The costs associated with facilities required to meet maximum hour demand are allocable to base, maximum day extra capacity, and maximum hour extra capacity as follows: Base = (1.0/2.6) x 100 = 38.5% Max Day = (2.6 — 1.0)/2.6 x 100 = 32.7% Max Hour = (2.6 — 1.85)/2.6 x 100 = 28.8% Figure 4-1 Illustrative Example of Capacity Demands 500 450 400 Maximum Hour Extra Capacity 350 m ,a 300 Maximum Day Extra Capacity 250 — — — — — — — — — — — - 0 200 150 Base Volume (Average Day) 100 19 Dec Jan Mar May Jun Aug Oct Nov Jan —Average Day —Maximum Day-Maxirrxni Hour For this Study, the average day, max day, and max hour factors are based on an average of three years of billing data. The calculated results, which followed the methodology outlined in Appendix A of the M1 Manual, indicate a max day factor of 1.90 (compared to the Master Plan value of 1.85) and a max hour factor of 2.54 (compared to the Master Plan of 2.60). 4.3.2 Allocation of Operating and Maintenance Expenses When allocating O&M expenses, the M1 Manual refers to functional cost components. Simply put, these cost costs correspond to the activities that the Water Utility undertakes to provide its customers with water: identify the water source, pump it, treat it, distribute it to customers, bill for services, and collect revenues. Where possible, the O&M expenses for FY 2025 are directly allocated to the cost components to the extent possible. For those costs that are not directly allocated to one cost center, Black & Veatch identified cost elements specific to certain functions and assigned them based on the factors noted in Section 4.1 to allocate the operating expenses to the cost components. Consider, for example, a storage BLACK & VEATCH I Cost -of -Service Analysis 12-34 City of Newport Beach, CA I Water Rate Study tank. Its purpose is to provide water during peak times. That is, when demand is greater than average, such as on a very hot summer day. The design of the storage tank is based on meeting maximum day needs. Therefore, the O&M costs for this tank are spread out between the base and max day elements. The elements general to all operations were allocated based on the average of all other costs. The direct assignment represents conservation, recycled water, and fire protection. Table 4-2 shows the allocation basis for operating costs, and Table 4-3 shows the total allocation of operating costs serving water customers. 4.3.3 Allocation of Capital Investments In allocating the capital investment for FY 2025, the existing fixed assets (which serve as a proxy for the capital investments) and proposed CIP are allocated directly to cost components to the extent possible. The allocation of costs in this manner provides a basis for annual investment in water system facilities. Using the existing fixed assets and CIP, the capital costs can be allocated using the total net system investment distribution across the functional cost components. Table 4-4 shows the allocation basis for capital expenditures, and Table 4-5 shows the allocation of existing system investment serving water customers. The total net system investment of $116.3M shown on Line 12 for the Water Utility represents the Test Year original cost less accumulated depreciation of the system in service for existing fixed assets and proposed CIP. The total net system investment reflects the Water Utility's fixed asset listing ending June 30, 2022. This value represents the original cost (book value) of the assets.

The billing determinant for costs with a volume component (e.g., purchased water) will be HCF or HCF/day. Billing costs will use the number of bills. Meter costs use an equivalent meter basis, and fire protection is based on equivalent hydrants. To properly recognize the cost of service, each customer class receives its share of base, maximum day, peak hour, and customer costs. Following the allocation of costs, the total cost responsibility for each customer class is developed using unit costs of service for each cost function and subsequently assigning those costs to the customer types based on the respective service requirements of each. The number of units of service required by each customer class provides a means for the proportionate distribution of costs previously allocated to respective cost categories. The derivation of the units of service for FY 2025 is as follows: Supply and base costs vary with the volume of water consumed and distributed to the customers on that basis. (HCF) (HCF/day) [1] [2]=[1]/365 Water 5.439.576 14.903 Recycled Water 244,511 670 Extra Capacity costs are those associated with meeting peak demand rates of water use and distributed to the customers based on the respective class capacity requirements more than average rates of use. The analysis followed the capacity factor methodology outlined in Appendix A of the AWWA M1 Manual to derive peak consumption information from the monthly consumption records in the City's Customer Information System, which helps estimate the maximum day and peak hour ratios.

The methodology in AWWA M1 was used to determine the max day and max hour capacities for fire services. It was assumed that fire protection requires flows for two simultaneous fires: (1) 3,000 gallons per minute (gpm) for a minimum of 3 hours for a commercial customer and (2) 1,000 gpm for 2 hours for a single-family residential customer. These are fire demand requirements put forth by the 2019 Water Master Plan.

Meter & service costs are those associated with operating and maintaining the water meters. Meter & service costs are distributed based on the estimated number of equivalent meters for each customer, which relies on the total number of meters serving respective types and the hydraulic capacity ratio of the meters to the 1/4" inch meter. The equivalent meter ratios adopted in this analysis are consistent with City meter types and the AWWA M1 Manual.

The total unit costs of service applied to the respective requirements for each customer class results in the total cost of service for each customer class. 4.5.1 Units Costs of Service The FY 2025 unit cost of service for each functional cost component is simply the total cost divided by the applicable units of service, as shown in Table 4-7. On Line 3, the total costs represent the cost that rates need to recover, as demonstrated in Table 4-1, Line 16. The net O&M cost includes O&M (including water purchase) less revenue from other sources and adjustments. Line 5 represents the unit costs for the entire water system regardless of customer type. After that, the unit costs are used to allocate the costs to the specific customer types. 4.5.2 Distribution of Costs of Service to Customer Types Applying the unit costs to the units for each customer class produces the customer class costs. This process is illustrated in Table 4-8, in which unit costs are applied to the customer class units of service for FY 2025. The costs attributable to each customer class reflect the functional cost components described in Section 4.1. Each customer class places a burden on the system in different ways; thus, the allocation of the units is representative of this burden. An example of the application of unit costs is shown below for illustrative purposes.

While the cost -of -service allocations to customer types should not be construed as literal or exact determinations, they offer a guide to the necessity and extent of rate adjustments. Practical considerations sometimes modify rate adjustments by considering additional factors such as the extent of bill impacts, existing contracts, and historical local policies and practices. 5.1 Existing Rates The existing rates of the Water Utility consist of a fixed component in the form of a monthly fixed service charge and a variable component in the form of a consumption charge. The monthly fixed service charge is based on meter size and applied regardless of consumption. The consumption charge is based on units of consumption (1 unit = 1 HCF = 748 gallons). The City has separate fixed charges for recycled water and private fire services. Table 3-3, presented earlier in this report, summarizes the existing water rates. 5.2 Proposed Rates The cost -of -service analysis described in the preceding sections of this report provides a basis for the design of water rates. 5.2.1 Monthly Fixed Service Charge The Water Utility provides water service to approximately 25,800 water service accounts and six recycled water accounts. These customers have dedicated water and recycled water line connections to the water systems. Therefore, water charges include capacity, water supply, public fire service costs, meter maintenance, and the cost of issuing bills. The following is a derivation of the different cost components that comprise the total charge. The numbers within the tables are rounded, but the calculations are based on non -rounded values. Differences are due to rounding. 5.2.1.1 Water Monthly Fixed Charge ■ Capacity Cost: The water system is designed to meet peak consumption demands plus fire demand requirements. Therefore, the water system will have extra capacity when handling average flow demands. To distribute the capacity costs, meter ratios based on maximum operating capacities by meter size were used, as shown in AWWA M1, Table B-1. Using meter ratios, we recognize that as meter size increases, so does the capacity. For example, customers with a 4" meter expect to be able to use more water (at a higher flow capacity) than customers with a 1/4" meter. Consequently, the City's water system must maintain assets sized accordingly and capable of providing customers the level of service expected from their meter connection when the tap turns on.

These include fixed and variable costs incurred by the water system while providing the average annual usage and peaking demands. While most costs are fixed, such as personnel and direct and indirect charges, variable costs represent most of the costs through water production and purchase.

A summary of actions and projections are as follows: Maintain the fixed service charge to reflect the nature of fixed costs associated with providing 24/7 water service and investments in infrastructure through the capital improvement program. Maintain the consumption charge to reflect the variable costs associated with operating costs, such as purchased water from wholesalers. Project water sales to remain flat in accordance with historical water demands and compliance with state water conservation targets. Operating Reserve. Strive to meet the fiscal policy of maintaining 33% of operating costs. Capital Reserves. Strive to maintain the minimum level of 75% of $7.5M capital costs. Rate Stabilization Reserve. Strive to meet the 30% of water use reduction target. Increase the annual investment in Capital Improvements from $7.5M to $10.2M by the end of the 5- year study period to reflect increased capital costs due to inflation. Maintain a comparable cost of delivering potable drinking water amongst neighboring water providers.

The City has not requested Black & Veatch to make an independent analysis, verify the information provided to us, or render an independent judgment of the validity of the information provided by others. Because of this, Black & Veatch cannot, and does not, guarantee the accuracy thereof to the extent that such information, data, or opinions were based on information provided by others. In conducting these analyses and in forming an opinion of the projection of future financial operations summarized in this report, Black & Veatch made certain assumptions on the conditions, events, and circumstances that may occur in the future. The methodology utilized in performing the analyses follows generally accepted practices for such projections. Such assumptions and methodologies are reasonable and appropriate for the purpose for which they are used. While we believe the assumptions are reasonable and the projection methodology valid, actual results may differ materially from those projected, as influenced by the conditions, events, and circumstances that occur. Such factors may include the City's ability to execute the capital improvement program as scheduled and within budget, regional climate and weather conditions affecting the demand for water, discharge of sewage flow, and adverse legislative, regulatory, or legal decisions (including environmental laws and regulations) affecting the City's ability to manage the system and meet water quality requirements. BLACK & VEATCH I Legal Notice LN-1 12-83 City of Newport Beach, CA I Sewer Rate Study 1.0 Executive Summary The City of Newport Beach (City) commissioned Black & Veatch Management Consulting, LLC (Black & Veatch) to perform a Sewer Rate Study (Study) for its Sewer Utility. The Study included the development of a five-year financial plan, a cost -of -service analysis, and the design of rates. The specific objectives of the Study were to: Evaluate the adequacy of projected revenues under existing rates to meet projected revenue requirements. Develop a sound financial plan for the Sewer Utility covering five years for ongoing operations and planned capital improvements. Allocate the projected revenue requirements to the various customer types in accordance with their respective service requirements. Develop a suitable rate schedule that produces revenues adequate to meet financial needs while recognizing customer costs of service and regulatory considerations such as Proposition 218 and applicable judicial decisions. 1.1 Financial Plan The City operates the utility as an individual self-supporting enterprise. As such, the utility develops a financial plan that provides sufficient revenues to meet all operation and maintenance (O&M) expenses, debt service requirements, capital improvements funded from current revenues, and other expenditures The Study develops a financial plan that projects operating revenue, expenses, and capital financing costs for the utility over a five-year planning period beginning July 1, 2023, and ending June 30, 2028. The financial plan projects future rate revenues under existing rates, O&M expenses, principal and interest expenses on debt, payment to other City departments for services provided, and capital improvement program (CIP) requirements. In the projection of rate revenues, annual projections of customers and contributed sewage flow rely upon the City's historical data and estimates of growth. The Sewer Utility's revenue requirements are summarized below: Operation and Maintenance Expenses: The Sewer Utility anticipates O&M expenses to increase from $5.1 M in FY 2024 to $6.1 M in FY 2028. The Sewer Utility is a collection -only system; City customers pay for treatment services to OC Sanitation District through their property tax bills. Debt Service: The Sewer Utility has no existing debt service, and no future debt is planned. Capital Improvements: The Sewer Utility plans to execute an average of $1.1 M annually in capital projects from FY 2024 to FY 2028. Reserves: The Sewer Utility plans to continue funding the operating fund reserve, capital fund reserve, and rate stabilization fund reserve. The operating fund reserve is to help cover fluctuations in day-to-day expenses. The scheduled target is 90 days of O&M expenses. The capital fund reserve is to help maintain enough funds to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs. The scheduled target is 100% of the annual CIP. BLACK & VEATCH I Executive Summary 12-84 City of Newport Beach, CA I Sewer Rate Study The Sewer Utility is proposing revenue adjustments and drawing down on reserves to allow the enterprise to meet operating and capital needs and reserve targets, as shown in Figure 1-1. Figure 1-1 Sewer Enterprise Fund Financial Plan Sewer Enterprise Fund 2W4 2025 2M6 2M 2M �O&M �Capital Projebts --o—Revenue Reserves 1.2 Cost of Service Analysis The cost -of -service analysis allocates the costs to the various customer types of service fairly and equitably. The methodology used in the Study is specific to the sewer utility operations. The following is a brief description of the methodology. The sewer cost -of -service allocation performed in this Study follows the Functional Cost Allocation Method endorsed by the Water Environment Federation (W EF) Financing and Charges for Wastewater Systems, Manual of Practice 27 (MoP27) manual. Like the methodology used for water systems, the sewer cost of service analysis allocates costs to the different customer types in proportion to their use of the sewer system. As recommended by WEF, Black & Veatch distributed functional costs to volume, strength, and customer -related parameters. This allocation methodology produces unit costs for allocation to individual customer types based on the projected customer service requirements. 1.3 Rate Design The Right to Vote on Taxes Act, also known as Proposition 218, was passed by California voters in 1996 and added Article XIIIC and Article XIIID to the California Constitution. These articles provide the regulatory framework that guides and informs the rate -setting process. The cost -of -service analyses provide the cost nexus for the proposed rate structures. The regulatory framework helps ensure cost recovery is proportionate to the cost of providing the service.' To minimize impacts, retain simplicity, and ensure the reasonable stability of revenue, Black & Veatch recommends the following rate structure. Monthly Fixed Charge: The Sewer Utility should retain the monthly fixed charge based on meter sizes for all customer types. The monthly fixed charge recovers portions of fixed cost elements such as operating and capital components, maintenance and services, and customer billing. ' Black & Veatch is not a legal firm and interpretations of the legal requirements under Proposition 218 should be reviewed by legal counsel. BLACK & VEATCH I Executive Summary 12-85 City of Newport Beach, CA I Sewer Rate Study Consumption Charge: The Sewer Utility should retain its uniform consumption charges for all customer types. The consumption charge recovers costs associated with volume demands. Table 1-1 summarizes all Sewer Utility components recommended five-year rate schedules. Rates will become effective January 1st of each calendar year.

Services include constructing and maintaining the sewer system and reducing sanitary sewer overflows. Sanitary sewer flows in the City are collected and transported through more than 203 miles of gravity and 5 miles of forced sewer mains by way of 21 lift stations to the Orange County Sanitation District (OC San) Plant No. 1 and No. 2. OC Sanitation District's regional treatment plants receive waste from 25 agencies in Orange County and can treat 179 million gallons a day (MGD) of liquid waste. 2.3 Methodology The rate -setting methodology employed by Black & Veatch is consistent with industry guidelines established by WEF's Financing and Charges for Wastewater Systems, Manual of Practice 27 manual. The manual is nationally recognized and provides recommendations and generally accepted practices in the sewer industry. The intent of the manuals is to provide rate -making practices that can be used to address the unique circumstances of the communities served. An overview of the methodology is outlined below. 2.3.1 Financial Plan Financial planning compares the projected revenues of the utility under existing conditions to its projected operating expenses and capital expenditures. This step tests the adequacy of the current rates to recover the utility's forecasted costs. If shortfalls occur, revenue increases are recommended until the utility is financially stable. 2.3.2 Cost -of -Service Analysis Financial Planning Establish operating and capital financing plans that fullyfund activities L_ The cost -of -service analysis builds a link customer classes between the utility's cost of service and IN - the proposed rates for each customer type. This process takes individual budget cost items and allocates them based on their function. Organizing the budget in terms of end function allows the creation of a nexus between the budget cost item and the rate. BLACK & VEATCH I Introduction 12-87 City of Newport Beach, CA I Sewer Rate Study 2.3.3 Rate Design Rate design involves developing a rate structure that equitably and proportionately recovers costs from the customers. The rate structure should reflect a customer group's demand profile and be resilient and flexible enough to handle changing costs (i.e., operating and/or capital) and demand scenarios (i.e., customers change their demand on the system by contributing less or more flow). Rate equity is inherently built upon each customer's Rate Design Review the existing rate structure + - and design proposed rates that provide adequate revenues relative use of the system. By designing different rate components, the utility can balance affordability and equity. 2.3.4 Rate Adoption In California, public utilities must meet procedural requirements for adopting new or increased rates for property -related fees under Proposition 218. Proposition 218 states that the utility must hold a public hearing to consider the proposed rates and provide written notice to all customers at least 45 days before the hearing. Any property owner or tenant directly liable to the public agency for payment of the property - related fees may submit a written protest to the new or increased rates until the close of the public hearing. The City Council may not adopt the proposed new or increased rates if property owners or tenants directly liable for payment submit written protests on behalf of more than 50% of the properties upon which the proposed rates may be imposed. BLACK & VEATCH I Introduction 2-2 12-88 City of Newport Beach, CA I Sewer Rate Study Sewer Utility 3.0 Revenue and Revenue Requirements To meet the costs associated with providing sewer services to its customers, the Sewer Utility derives revenue from various sources, including sewer user charges (rates), collections, penalties, interest earned from the investment of available funds, and other miscellaneous revenues. The Sewer Utility is constantly looking for other sources of revenue, such as grants, to help mitigate ratepayer impacts. The level of future revenues is estimated via an analysis of historical and future system growth in terms of the number of accounts and contributed sewage flow. This section also projects the expenses, or revenue requirements, necessary to operate and maintain the system, invest in capital improvements, make debt service payments, and cover other sewer system expenses. 3.1 Customer and Water Consumption Projections 3.1.1 No. of Customers The City provides sewer collection services to 23,500 residential and non-residential customers. Most customers connected to the sewer system are water customers and, therefore, are connected through metered connections. The City also provides sewer -only service to over 500 City customers who receive water from Mesa Water District or Irvine Ranch Water District. The City bills customers based on the size of the water -metered connection and the contributed sewage flow. Since the City bills customers based on the metered connection, the analysis included a review of historical accounts for customers and anticipated growth within the City. The City has seen three straight years of decline in population between 2020 and 2023 based on the State of California, Department of Finance, E-5 Population and Housing Estimates. The projected number of accounts will remain steady for the entire study period. Table 3-1 summarizes the projected number of accounts for the Sewer Utility.

In determining the projected contributed sewage flow, Black & Veatch analyzed historical sewage flow patterns in conjunction with the water projections for the Water Utility. Contributed sewage flows equal water consumption; therefore, it is important to understand water consumption patterns. In examining water consumption patterns, it was noted that water consumption depends on California's weather conditions. Water consumption has stabilized over the past few years due to water conservation incentives and messaging. Recognizing that water consumption has stabilized, the projected contributed sewage flow is expected to remain steady for the Study period. The City currently bills contributed sewage flow in hundred cubic feet (HCF).

Therefore, the level of future rate revenue is important in developing a long-range financial plan. Future sewer rate revenues are calculated using the number of accounts and billed sewage flow multiplied by the applicable existing rates. Table 3-3 shows the Sewer Utility's current schedule of charges. The rates are composed of monthly fixed and uniform consumption charges. The monthly fixed service charge is the same for all customers except sewer -only customers. The difference is that the monthly fixed service charge for sewer -only customers includes a contributed sewage flow based on the average water consumption for that meter size. The consumption charge is the same for all customers based on water flow.

In 2008, the City completed its Wastewater Master Plan, which identified $29.OM in capital projects in 2008 costs. Incorporating cost escalation over the 30 years, the City had planned to spend roughly $1.1 M each year. Unfortunately, due to higher -than -expected inflation, the City has readjusted the capital spend by escalating the annual $1.1 M by 5% each year except for FY 2024. The total CIP over the Study period totals $5.5M. Table 3-7 summarizes the CIP for FY 2024 through FY 2028. The Sewer Utility's main activities are related to the collection system. As such, of the total $5.5M CIP, collection mains account for 64.2% of the total projects. The City examines the sewer infrastructure system annually; therefore, CIP might change based on the current need.

The other funds are the Enterprise CIP, Capital, and Operating Reserve. See Section 3.7 for further explanation on Operating Reserve and Rate Stabilization Funds. The Enterprise CIP and Capital transfers represent money to cover planned CIP project expenditures. These transfers do not represent direct operating expenses for either enterprise; therefore, Black & Veatch includes these costs as "below - the -line" cash flow items and does not include them as O&M expenses. 3.7 Reserves A utility typically establishes reserves for several reasons, such as to cover shortfalls in operating revenues, maintain strong bond ratings, cover day-to-day operating costs, and ease the burden on ratepayers associated with large rate increases. Per the reserve level recommendations, the Sewer Utility will maintain the following two reserves: Operating Reserve represents the working capital the Enterprise Fund maintains to cover day-to- day expenses and maintain enough funds to cover accounts receivables if there are supplier issues, periods of lower -than -expected sewer sales, or unforeseen cost increases. The reserve will maintain a minimum balance of 90 days of operating expenses once fully funded. Capital Reserve represents funds to cover a portion of upcoming annual capital expenditures, smooth out the amount of capital infusion needed each year, and help mitigate unexpected capital costs. Once fully funded, this reserve will maintain a minimum balance of 100% of the annual planned CIP. BLACK & VEATCH I Revenue and Revenue Requirements 12-93 City of Newport Beach, CA I Sewer Rate Study Appropriate reserve levels help the Sewer Utility with liquidity, provide operational flexibility, and demonstrate fiscal responsibility to the rating agencies, which allows the City to access lower -cost funds.

To fully understand the current condition of the Sewer Utility, it is important to examine the cash flow projections under the status quo scenario. As shown in Figure 3-2, the status quo conditions indicate that the Sewer Utility would operate from an annual deficit position, requiring the drawdown of reserves to keep operating. In this scenario, the Sewer Utility would not impose any revenue increases over the Study Period and continue to incur O&M expenses and pay for the execution of the planned CIP.

The revenue increases represent the total revenue adjustment needed to meet revenue requirements. The revenue adjustment does not represent adjustments to the individual rates but reflects the overall level of revenue needed to meet the Sewer Utility's obligations. The recommended revenue increases help the Sewer Utility meet the following goals: Meet budgeted operating obligations in the five FYs. Meet planned capital investments in the five FYs. Build up the operating reserve and capital reserve to get closer to their target. Table 3-8 summarizes the proposed Enterprise Fund for the Study Period. The Enterprise Fund consists of 1) Revenue and 2) Revenue Requirements. Ravani is Line 1 is the revenue under existing rates. Lines 2 through 6 are the additional revenues generated from the required annual increases. The additional revenue generated directly reflects the number of months the increase is effective for; therefore, the amount might be calculated at less than that stated amount. Line 8 is the total revenue generated from user charges. Line 11 represents other operating revenues. Line 12 represents the total revenues for the enterprise.

An equitable rate structure allocates the capture of revenue requirements to customer types based on the contributed sewage flow and the number of customer connections. In analyzing the Sewer Utility's cost of service for allocation to its customer types, Black & Veatch selected the annual revenue requirements for FY 2024 as the test year requirements to demonstrate the development of cost -of -service sewer rates. Table 4-1 summarizes the total costs of service that need to be recovered from sewer user rates for FY 2024. Table 4-1 Cost of Service Revenue from Rates (FY 2024) ®Operatin Expense Revenue Requirements 1 D&M Expense 5,097,900 0 5,097,900 2 Debt Service Requirements 0 0 0 3 Transfers far Capital Projects (3,132,600) 750,000 (2,3S2,600) 4 Subtotal 1,965,300 750,000 2.715.300 Less Revenue Requirements Met from Other Sources 5 Miscellaneous 0 0 0 ,6 I nterfund Tra nsFers 16,500 0 16,500 7 Dther Income 10,000 0 10.000 8 Interest 40,400 0 40.400 9 Capital Financing 0 0 0 10 Subtotal $ 66,900 $ 0 66.900 Adjustments 11 Adj for Annual Cash Balance {115581WO) {555,40D) (2,314,200) 12 Adj to Annualize Rate Increase (318,700) (125,90D) (444,600) 13 Subtotal $ (1,977,500) $ (791,300) (2,758,&00) 14 COS to be Recovered from Rates $ 3,S75,900 $ 1,531,300 $ 5.407.200 The total revenue requirement is shown in Line 4. As shown in Line 10, we deduct revenues from other sources to derive the net revenue requirement recovered through rates. Line 11 represents the net annual cash balance during the FY. This number is positive if the enterprise is drawing down funds already in the Enterprise Fund. The number will be negative if the enterprise is replacing funds. In this case, the $(2.3M) figure indicates that the forecast is projecting a positive annual cash balance for the year. Line 14 represents the additional revenues generated if the revenue increase was effective for a full year versus only 5 months. 4.1 Functional Cost Components The first step in conducting a cost -of -service analysis involves analyzing the cost of providing sewer service by system function to allocate the costs to the various customer types properly and, subsequently, design rates. As a basis for allocating costs of service among customer types, costs are separated into the following two basic functional cost components: (1) Volume and (2) Customer, described as follows: BLACK & VEATCH I Cost -of -Service Analysis 12-98 City of Newport Beach, CA I Sewer Rate Study Volume costs represent the operating and capital costs of the system associated with collection. The collection costs vary directly with the quantity of contributed sewage flow. Customer costs are those expenditures that tend to vary in proportion to the number of customers and capacity needed to serve these customers. These include meter reading, billing, collecting, accounting, maintenance, and capital costs associated with meters and services. 4.2 Allocation to Cost Components The next step of the cost -of -service process involves allocating each cost element to functional cost components based on the parameter or parameters having the most significant influence on the magnitude of that cost element. O&M expenses are allocated directly to appropriate cost components. A detailed allocation of related capital investment is used as a proxy for allocating capital and replacement costs. The separation of costs into functional components provides a means for distributing such costs to the various categories of customers based on their respective responsibilities for each type of service. 4.2.1 Volume Allocations The sewer system consists of various facilities designed and operated to fulfill a given function. For the system to provide adequate service to its customers, it must be capable of meeting the annual volume requirements. Because not all customers and types of customers exert volume demands similarly, the capacities of the various facilities must be designed to accommodate the demands of all categories of customers. Each sewer service facility within the system has an underlying volume demand exerted by all customers for whom the volume cost component applies. For those facilities designed solely to meet volume demand, 100% of the costs go to the volume cost component. 4.2.2 Allocation of Operating and Maintenance Expenses In allocating O&M expenses for FY 2024, costs are directly allocated to the cost components to the extent possible. The Sewer Utility does not categorize operating costs by functional categories such as collection, lift stations, treatment, etc. Therefore, the analysis identified cost elements specific to certain functions and assigned them based on the factors noted in Section 4.1 to allocate the operating expenses to the cost components. Table 4-2 shows the allocation basis for operating costs, and Table 4-3 shows the total allocation of operating costs serving sewer customers.

The allocation of costs in this manner provides a basis for annual investment in sewer system facilities. Using the existing fixed assets and CIP, the capital costs can be allocated using the total net system investment distribution across the functional cost components. Table 4-4 shows the allocation basis for capital expenditures, and Table 4-5 shows the allocation of existing system investment serving sewer customers. The total net system investment of $28.2M shown on Line 5 for the Sewer Utility represents the test year original cost less accumulated depreciation of the system in service for existing fixed assets and proposed CIP. The total net system investment reflects the Sewer Utility's fixed asset listing ending June 30, 2022. This value represents the original cost (book value) of the assets.

The billing determinant for costs with a volume component will be HCF or HCFf/day. Customer costs will use equivalent meters. To properly recognize the cost of service, each customer class receives its share of volume and customer costs. Following the allocation of costs, the total cost responsibility for each customer class is developed using unit costs of service for each cost function and subsequently assigning those costs to the customer types based on the respective service requirements of each. The number of units of service required by each customer class provides a means for the proportionate distribution of costs previously allocated to respective cost categories. Volume costs vary with the volume of contributed sewage flow produced and distributed to customer types on that basis. Contributed sewage flow information comes from the monthly water consumption records in the City's customer billing system. (HCF) All Customers 4,030,872 Sew er On ly 200,376 Customer billing costs are distributed on an equivalent meter basis for each customer. The estimated number of equivalent meters for each customer relies on the number of meters serving respective categories and the capacity ratio of the meters to the 1-inch meter. The equivalent meter ratios adopted in this analysis are lower than those used for water, as wastewater system peaking is less widespread than water. The range for equivalent meters ranges from 1.0 to 5.0.

The total unit costs of service applied to the respective requirements for each customer class results in the total cost of service for each customer class. 4.4.1 Units Costs of Service The FY 2024 unit cost of service for each functional cost component is simply the total cost divided by the applicable units of service, as shown in Table 4-7. On Line 3, the total costs represent the cost that rates need to recover, as demonstrated in Table 4-1, Line 14. The net O&M cost includes O&M less revenue from other sources and adjustments. Line 5 represents the unit costs for the entire sewer system regardless of customer type. After that, the unit costs are used to allocate the costs to the specific customer types. 4.4.2 Distribution of Costs of Service to Customer types Applying the unit costs to the units for each customer class produces the customer class costs. This process is illustrated in Table 4-8, in which unit costs are applied to the customer class units of service for FY 2024. The costs attributable to each customer class reflect the functional cost components described in Section 4.1. Each customer class places a burden on the system in different ways; thus, the allocation of the units is representative of this burden.

While the cost -of -service allocations to customer types should not be construed as literal or exact determinations, they offer a guide to the necessity and extent of rate adjustments. Practical considerations sometimes modify rate adjustments by considering additional factors such as the extent of bill impacts, existing contracts, and historical local policies and practices. 5.1 Existing Rates The existing rates of the Sewer Utility consist of a fixed component in the form of a monthly fixed service charge and a variable component in the form of a consumption charge. The monthly fixed service charge is based on meter size and applied regardless of consumption. The consumption charge is based on units of consumption (1 unit = 1 HCF = 748 gallons). Table 3-3, presented earlier in this report, summarizes the existing sewer rates. 5.2 Proposed Rates The costs of service analysis described in the preceding sections of this report provide a basis for designing sewer rates. 5.2.1 Monthly Fixed Service Charge The Sewer Utility provides sewer service to approximately 23,500 sewer service accounts. These customers have a dedicated sewer line connection to the wastewater system. Therefore, sewer charges include capacity and cost of issuing bills. The following is a derivation of the different cost components that comprise the total charge. The numbers within the tables are rounded, but the calculations are based on non -rounded values. Differences are due to roundin_p. 5.2.1.1 Sewer Monthly Fixed Charge ■ Capacity Cost: The sewer system is designed to meet peak wet wastewater flow demand requirements. Therefore, the sewer system will have extra capacity when handling average contributed sewage flow demands. Meter ratios based on operating capacities derived in the 2017 rate study were used to distribute the capacity costs. Using meter ratios, we recognize that as meter size increases, so does the capacity. For example, customers with a 4" meter expect to be able to use more water (and generate more contributed sewage flow) than customers with a %" meter. Consequently, the City's sewer system must maintain assets sized accordingly and capable of providing customers the level of service expected from their sewer connection when they flush the toilet.

The consumption charges are the same for all customers regardless of the metered size connection. The consumption charge is billed per HCF and is uniform for all customer types, as the City's contributed sewage flow is only related to conveyance and not treatment. OC Sanitation handles treatment services. Based on the analysis for FY 2024, the proposed consumption rate of $0.53 per HCF is paid by all customers. The rate is based on metered water use and recognizes BLACK & VEATCH I Rate Design 12-105 City of Newport Beach, CA I Sewer Rate Study that irrigation flow is inherently incorporated. Any customer types with significant irrigation water use have a dedicated irrigation metered connection and thus are not charged sewer consumption charges. The use of metered water use will unavoidably include some irrigation water. Figure 5-1 summarizes the Newport Beach area's average high temperature and precipitation between 2012 and 2022. Over the past 10 years, the average high temperature is 68.6°F, with a standard deviation of 4.3°. Over this period, the average daily precipitation is 0.02 inches. Data from the National Oceanic and Atmospheric Administration and similar weather sites shows that these trends were similarly exhibited for the past 32 years: the Newport Beach area experiences consistent temperatures year-round and little rainfall. Since there is not a large variance in temperature year-round, it is reasonable to assume that summer consumptive behavior will be consistent with winter consumptive behavior. The historically dry winters experienced by the Newport Beach area also mean that winter -time irrigation also occurs. Therefore, using a winter average consumption to determine contributed sewage flow will provide the same results as using water consumption, and thus, using water usage as a basis for sewer consumption charges is a reasonable proxy.

Since the City does not meter the water consumption for these customers, the average water consumption by meter size was used to assign an allowance for contributed sewage flow. The average water consumption by meter size is identified in Table 5-5, along with the five-year sewer -only charges. The following is an example of the calculation performed for sewer -only customers for 1-inch meters.

A summary of actions and projections are as follows: Maintain the fixed service charge to reflect the nature of fixed costs associated with providing 24/7 sewer service and investments in infrastructure through the capital improvement program. Maintain the consumption charge to reflect the variable costs associated with operating costs such as utilities. Project sewer sales to remain flat in accordance with historically contributed sewage flow and compliance with state water conservation targets. State water conservation target impact contributed sewer flow. Operating Reserve. Strive to meet the fiscal policy of maintaining 25% of operating costs. Capital Reserves. Strive to maintain the minimum 75% of $1.1 M capital costs. Increase the annual investment in Capital Improvements from $1.1 M to $1.3M by the end of the 5- year study period to reflect the increase in capital costs due to inflation. Maintain a comparable cost of collecting contributed sewage flow amongst neighboring sewer collection -only providers.

ATTEND IN PERSON Council Chambers 100 Civic Center Drive, Newport Beach, CA 92660 The Utilities Department invites you to attend and participate in this public hearing. The City Council will consider adopting the proposed water and sewer rate increases. WATER AND SEWER RATE INCREASE KEEPING PACE WITH RISING COSTS rroposea Kate Increase In compliance with Proposition 218, the City is notifying all customers about proposed changes to the City`s water and sewer rate charges. You are receiving this notice because you are a customer of the City of Newport Beach. Of utmost importance is the effort to minimize costs, including rates, while maintaining the integrity and reliability of the City`s infrastructure and its financial stability. To assist the City in this endeavor, an independent outside financial consultant who specializes in cost of service analysis and rate setting was retained by the City. r ; R ADDITIONAL INFORMATION Please Visit Oui- WebwLV. www.newportbeachca.gov/trending under "Projects" The Utilities Department has created a comprehensive website that houses all the relevant information along with the detailed rate studies. apu UTILITIES DEFT NEWPORT BEACH NOTICE OF PUBLIC HEARING SUMMARY The City is writing to inform you of proposed changes to the rates we charge for your water and sewer services. If approved by City Council, these changes will take effect on your billing statements beginning January 1, 2024. These proposed increases are the result of detailed budget analysis and the findings of recent City Water and Sewer Rate Study Reports (Rate Study). The reports were prepared by an independent financial firm to determine a fair and equitable cost allocation among water and sewer customer categories. Typical monthly increases for the most common customers will be: (Example: with a 5/8-inch meter using10 HCF Hundred Cubic Feet, i.e. 7,480 gallons per month) For water, $4.77 in 2024, $5.50 in 2025, $6.00 in 2026, $6.00 in 2027, $6.00 in 2028 For sewer, $2.20 in 2024, $2.50 in 2025, $3.00 in 2026, $3.50 in 2027, $3.50 in 2028 The net impact of the proposed changes in the rates for water customers will vary based upon actual water consumption and meter size. BACKGROUND Every few years, as the current rate schedules expire, separate financial plan and rate studies are necessary to evaluate the water and sewer rates, determining the charge for customers. Rate studies were previously completed in 2017 for sewer and in 2019 for water. These studies represent a best practice for determining utility rates that are fair, equitable and reflective of the demand placed on the systems by the customers. The goal was to ensure the City's plans for critical infrastructure maintenance, accounting for inflation, and funding capital improvement projects with cash, were in alignment with proposed rates. Our mission is to continue providing high -quality and local control water and sewer services at the best value for Newport Beach. These water and sewer services are separately tracked and are funded through the revenue collected from your municipal services statement, i.e. water and sewer bill. No taxes or property taxes are received for your water and sewer services, and there is no debt on the system, so the City must align rates with the cost to deliver services. Costs include (1) the cost to supply and treat water, (2) compliance with governing regulations, (3) the repair, replacement, and update of aging systems, and (4) ongoing maintenance of this critical infrastructure. Like any asset, regular maintenance and replacement are critical to operate the City's water and sewer systems. Over the past four years, we have invested in tens of millions of dollars in pipeline and pump station replacements and upgrades. Over the next five years, we are continuing that ongoing investment with over $45 million in water and sewer capital replacements and upgrades. Among other projects, we'll continue to rehabilitate our water storage reservoirs, groundwater wells, pump stations and replace/rehabilitate miles of pipelines. This will include complex underwater work for lines that run beneath Newport Harbor. We take seriously the maintenance and replacement of the systems, as well as the trust you've placed in us to deliver high quality water and sewer services, and we adjust rates only when necessary. Should you have any questions about the proposed changes, please visit our website or newportbeachca.gov/trending under "Projects" or contact the Utilities Department at 949-644-3011. Thank you for your support and understanding. Mark Vukojevic, Utilities Director THE WATER SYSTEM The City of Newport Beach Utilities Department manages the City's water system. Our water is sourced by a blend of up to 85% ground water and 15% imported surface water. Newport's groundwater comes from four ground water wells Located in the City of Fountain Valley, then pumped to a reservoir in Newport Beach. The groundwater basin is actively managed by Orange County Water District (OCWD, www.ocwd.com). Ground water comes from a natural under ground aquifer, Layered with sand and gravel, that works as a natural water filter. The water is replenished with water from the Santa Ana River, local rainfall, imported water and the Ground Water Replenishment System (GWRS). The imported surface water is primarily from the Colorado Aqueduct (Colorado River) and sometimes water from the California Aqueduct (Northern California). The Utilities Department maintains and operates the City's water system which includes 4 groundwater wells, 3 water storage reservoirs, 17 pumps and 42 pressure reduction stations. Additionally, the department oversees recycled water services, manages over 300 miles of water distribution pipelines, maintains over 25,000 service lines, and over 2,500 fire hydrants to distribute water to the homes and businesses of Newport Beach. THE SEWER SYSTEM The City of Newport Beach Utilities Department also manages the sewer system, providing service to residential and commercial customers. The City's system is a collection and transportation system; the Orange County Sanitation District (OC San) Huntington Beach plant provides treatment services. Sanitary sewer flows are collected from Newport Beach residences and businesses and transported through more than 25,000 laterals, 200 miles of gravity sewer mains and 5 miles of pressurized force sewer mains by way of 21 pump (lift) stations to OC San.
